Lilith once said that within the Supreme Mother River, there are countless worlds, including Abysses and realms like the Pure White Heaven, which shine upon numerous smaller realms at the top of the ecological hierarchy.
But among them, there are only three Main Worlds, also known as the Eternal Worlds.
They symbolize worlds that have existed and will exist forever!
They occupy the mainstream positions near the source of the Mother River, drawing the most nutrients, and are still growing, incapable of self-destruction.
The Beast Master Realm where Gary resides is one of them.
Being born there is like reaching the endpoint for others!
As for the other two Main Worlds, Gary asked Lilith for details, not that she would refuse to tell him unless she were coerced, but because she herself didn't know either.
Despite her weird XP, this spider Succubus is surprisingly honest!
